ABSTRACT

The disclosed computer-implemented method for authenticating users on touchscreen devices may include (i) detecting that the computing device is at an authentication step that requires valid authentication input from a user in order to authenticate the user to a service on the computing device, (ii) detecting that the computing device is physically oriented such that a touchscreen of the computing device is facing away from the user of the computing device, (iii) receiving input from the user via the touchscreen, (iv) determining that the input from the user comprises a mirrored version of the valid authentication input that is flipped along a vertical axis relative to the touchscreen, and (v) authenticating the user to the service in response to determining that the input comprises the mirrored version of the valid authentication input. Various other methods, systems, and computer-readable media are also disclosed.

BACKGROUND

Many people carry mobile devices such as smartphones and tablets and interact with these devices frequently. Security-conscious users often lock their device with a passcode that must be entered before the device can be used. When entering device unlock codes in public spaces, such as on public transportation or in a crowd, it is not difficult for a bystander to observe a user's passcode. There is a similar problem when people enter passcodes at an automated teller machine (ATM). Usually, a user at an ATM will enter the passcode with one hand and use the other hand to block line of sight to the keypad, preventing bystanders from learning the user's passcode. However, this method is awkward with a mobile device, where typically a user will need to hold the device with one hand, especially when a user is in public and has nowhere to put the device down.

With traditional systems for authentication, users have limited options. A user may put their phone inside a bag or a backpack to reduce visibility to bystanders, but this method reduces visibility for the user, as well as being inconvenient and potentially drawing unwanted attention from bystanders. A user may also choose to wait to authenticate to their device until there are no bystanders, but this may be impractical for many situations. Accordingly, the instant disclosure identifies and addresses a need for additional and improved systems and methods for authenticating users on touchscreen devices.

SUMMARY

As will be described in greater detail below, the instant disclosure describes various systems and methods for authenticating users on touchscreen devices by detecting when a device has been turned so that the touchscreen faces down and accepting a mirrored version of the usual passcode in such situations.

In one example, a computer-implemented method for authenticating users on touchscreen devices may include (i) detecting that the computing device is at an authentication step that requires valid authentication input from a user in order to authenticate the user to a service on the computing device, (ii) detecting that the computing device is physically oriented such that a touchscreen of the computing device is facing away from the user of the computing device, (iii) receiving input from the user via the touchscreen, (iv) determining that the input from the user includes a mirrored version of the valid authentication input that is flipped along a vertical axis relative to the touchscreen, and (v) authenticating the user to the service in response to determining that the input includes the mirrored version of the valid authentication input.

In some examples, authenticating the user to the service on the computing device may include unlocking the computing device. In some embodiments, determining that the input may be a mirrored version of the valid authentication input may include determining that the valid authentication input includes a group of ordered components and determining, for each ordered component within the ordered components, that the currently entered component of the input from the user is a mirrored version of the ordered component that corresponds to the correct position in the ordered components.

In some embodiments, receiving the input from the user via the touchscreen may include detecting that the user has entered a component of the input and providing the user with an acknowledgement that the component of the input has been received by the computing device. In some examples, providing the user with the acknowledgement may include vibrating the computing device.

In some examples, detecting that the computing device is at the authentication step may include receiving input from the user that triggers the authentication step. In one embodiment, detecting that the computing device is physically oriented such that the touchscreen of the computing device is facing away from the user of the computing device may include using an accelerometer within the computing device to determine the physical orientation of the computing device.

In some embodiments, the computing device may include a mobile device. In one embodiment, the valid authentication input may include a series of shapes drawn on the touchscreen. Additionally or alternatively, the valid authentication input may include a series of presses at a series of points on the touchscreen.

In one embodiment, a system for implementing the above-described method may include (i) a detection module, stored in memory, that detects that the computing device is at an authentication step that requires valid authentication input from a user in order to authenticate the user to a service on the computing device and detects that the computing device is physically oriented such that a touchscreen of the computing device is facing away from the user of the computing device, (ii) a receiving module, stored in memory, that receives input from the user via the touchscreen, (iii) a determination module, stored in memory, that determines that the input from the user includes a mirrored version of the valid authentication input that is flipped along a vertical axis relative to the touchscreen, (iv) an authentication module, stored in memory, that authenticates the user to the service in response to determining that the input includes the mirrored version of the valid authentication input, and (v) at least one physical processor configured to execute the detection module, the receiving module, the determination module, and the authentication module.

In some examples, the above-described method may be encoded as computer-readable instructions on a non-transitory computer-readable medium. For example, a computer-readable medium may include one or more computer-executable instructions that, when executed by at least one processor of a computing device, may cause the computing device to (i) detect that the computing device is at an authentication step that requires valid authentication input from a user in order to authenticate the user to a service on the computing device, (ii) detect that the computing device is physically oriented such that a touchscreen of the computing device is facing away from the user of the computing device, (iii) receive input from the user via the touchscreen, (iv) determine that the input from the user includes a mirrored version of the valid authentication input that is flipped along a vertical axis relative to the touchscreen, and (v) authenticate the user to the service in response to determining that the input includes the mirrored version of the valid authentication input.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

The present disclosure is generally directed to systems and methods for authenticating users on touchscreen devices. As will be explained in greater detail below, by accepting a mirrored version of a valid passcode as valid, the systems and methods described herein may enable users to log in to their mobile devices with the device face-down, preventing others from seeing the passcode, while still allowing users to enter their passcode in an intuitive manner.

The following will provide, with reference to FIGS. 1-2, detailed descriptions of example systems for authenticating users on touchscreen devices. Detailed descriptions of corresponding computer-implemented methods will also be provided in connection with FIG. 3.

FIG. 1 is a block diagram of example system 100 for authenticating users on touchscreen devices. As illustrated in this figure, example system 100 may include one or more modules 102 for performing one or more tasks. For example, and as will be explained in greater detail below, example system 100 may include a detection module 104 that detects that a computing device is at an authentication step that requires valid authentication input from a user in order to authenticate the user to a service on the computing device and that also detects that the computing device is physically oriented such that a touchscreen of the computing device is facing away from the user of the computing device. Example system 100 may additionally include a receiving module 106 that receives input from the user via the touchscreen. Example system 100 may also include a determination module 108 that determines that the input from the user includes a mirrored version of the valid authentication input that is flipped along a vertical axis relative to the touchscreen. Example system 100 may additionally include an authentication module 110 that authenticates the user to the service in response to determining that the input includes the mirrored version of the valid authentication input. Although illustrated as separate elements, one or more of modules 102 in FIG. 1 may represent portions of a single module or application.

In certain embodiments, one or more of modules 102 in FIG. 1 may represent one or more software applications or programs that, when executed by a computing device, may cause the computing device to perform one or more tasks. For example, and as will be described in greater detail below, one or more of modules 102 may represent software modules stored and configured to run on one or more computing devices, such as computing device 202 in FIG. 2, computing system 610 in FIG. 6, and/or portions of example network architecture 700 in FIG. 7. One or more of modules 102 in FIG. 1 may also represent all or portions of one or more special-purpose computers configured to perform one or more tasks.

Example system 100 in FIG. 1 may be implemented in a variety of ways. For example, all or a portion of example system 100 may represent portions of example system 200 in FIG. 2. As shown in FIG. 2, system 200 may include a computing device 202. In one example, computing device 202 may be programmed with one or more of modules.

In one embodiment, one or more of modules 102 from FIG. 1 may, when executed by at least one processor of computing device 202, enable computing device 202 to authenticate users on touchscreen devices. For example, and as will be described in greater detail below, detection module 104 may detect that computing device 202 is at an authentication step 208 that requires valid authentication input 212 from a user in order to authenticate the user to a service on computing device 202. At the same time, detection module 104 may also detect that computing device 202 is physically oriented such that a touchscreen of computing device 202 is facing away from the user of computing device 202. Soon afterwards, receiving module 106 may receive input 210 from the user via the touchscreen. Next, determination module 108 may determine that input 210 from the user is a mirrored version of valid authentication input 212 that is flipped along a vertical axis relative to the touchscreen. Finally, authentication module 110 may authenticate the user to the service in response to determining that input 210 is a mirrored version of valid authentication input 212.

Computing device 202 generally represents any type or form of computing device capable of reading computer-executable instructions. In some embodiments, computing device 202 may be a smart phone such as an IPHONE or ANDROID device. Further examples of computing device 202 include, without limitation, laptops, tablets, desktops, servers, cellular phones, Personal Digital Assistants (PDAs), multimedia players, embedded systems, wearable devices (e.g., smart watches, smart glasses, etc.), gaming consoles, combinations of one or more of the same, example computing system 610 in FIG. 6, or any other suitable computing device.

FIG. 3 is a flow diagram of an example computer-implemented method 300 for authenticating users on touchscreen devices. The steps shown in FIG. 3 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 3 may be performed by one or more of the components of system 100 in FIG. 1, system 200 in FIG. 2, computing system 610 in FIG. 6, and/or portions of example network architecture 700 in FIG. 7.

As illustrated in FIG. 3, at step 302, one or more of the systems described herein may detect that a computing device is at an authentication step that requires valid authentication input from a user in order to authenticate the user to a service on the computing device. For example, detection module 104 may, as part of computing device 202 in FIG. 2, detect that computing device 202 is at an authentication step 208 that requires valid authentication input 212 from a user in order to authenticate the user to a service on computing device 202.

The term “authentication step,” as used herein, generally refers to any situation where a user must authenticate before proceeding. For example, an authentication step may be a phone unlock screen that a user must authenticate to before performing further actions on the phone. In another example, an authentication step may be a login screen for an application and/or a website. In some examples, an authentication step may occur after a user has already authenticated to a service, such as when the user is changing important settings and/or performing important transactions. For example, a user who is attempting to change their password may be prompted with an authentication step to enter their old password before confirming the new password. In another example, a user who is transferring money via a website may be prompted to re-enter their password before confirming the transfer.

The term “valid authentication input,” as used herein, generally refers to any input that may be provided by a user that authenticates the user to a service. In some examples, authentication input may include a password and/or passcode. In one embodiment, the valid authentication input may include a series of shapes drawn on the touchscreen. For example, the valid authentication input may be a squiggly line, a triangle in the upper left corner of the screen, and/or a square drawn in a certain order (e.g., starting at the lower left corner and proceeding clockwise). In another example, a series of shapes may be a series of letters, numbers and/or other characters that form a password. For example, if a user's pass phrase were “malicious toaster,” the series of shapes would be “m,” “a,” “l,” “i,” “c,” “i,” and so forth. In some examples, a series of shapes may be a single shape. Additionally or alternatively, the valid authentication input may include a series of presses at a series of points on the touchscreen. For example, the valid authentication input may include pressing the upper right corner of the screen, the lower right corner of the screen, the upper left corner of the screen, and then the lower left corner of the screen, in that order. In another example, the series of presses may correspond to icons on the touchscreen. For example, a series of presses over icons representing the numbers “1,” “2,” “1,” and “0” may be used to enter the numerical passcode “1210.”

The term “service,” as used herein, generally refers to any application, website, feature, and/or functionality that may be accessed on a computing device. In some examples, the service may be an authentication service for a mobile device and authenticating to the service may unlock the mobile device. In other examples, the service may be an app, a website, and/or a password-protected feature of the computing device.

Detection module 104 may detect that the computing device is at an authentication step in a variety of ways. In some examples, detection module 104 may detect that the computing device is at the authentication step by receiving input from the user that triggers the authentication step. For example, the user may press an unlock button on their mobile phone, triggering an authentication step.

At step 304, one or more of the systems described herein may detect that the computing device is physically oriented such that a touchscreen of the computing device is facing away from the user of the computing device. For example, detection module 104 may, as part of computing device 202 in FIG. 2, detect that computing device 202 is physically oriented such that a touchscreen of computing device 202 is facing away from the user of computing device 202.

The term “touchscreen,” as used herein, generally refers to any portion of a device that allows a user to interact with the device by touching areas on a screen. In some embodiments, the touchscreen may be a touchscreen on a mobile device. The term “facing away from the user,” as used herein, may generally refer to situations where the touchscreen of a device is positioned so that it is not directly visible to the current user of the computing device. For example, detection module 104 may detect that the touchscreen is facing away from the user if the touchscreen is rotated more than 90° away from the user along any axis. In some embodiments, the touchscreen may be facing away from the user because the touchscreen is facing downwards (e.g., parallel or nearly parallel with, and facing, the ground or floor). In one embodiment, detection module 104 may detect that a touchscreen is facing downwards if the touchscreen is within a predetermined angle of facing downwards. For example, if the computing device is within a 20° angle of being horizontal and the touchscreen angled is towards the floor, detection module 104 may detect that the touchscreen is facing downwards. In another embodiment, if the computing device is within a 60° angle of being horizontal and the touchscreen is on the downwards side, detection module 104 may detect that the touchscreen is facing downwards.

Detection module 104 may detect the orientation of the computing device in a variety of ways. In some embodiments, detection module 104 may use an accelerometer within the computing device to determine the physical orientation of the computing device.

At step 306, one or more of the systems described herein may receive input from the user via the touchscreen. For example, receiving module 106 may, as part of computing device 202 in FIG. 2, receive input 210 from the user via the touchscreen.

The term “input,” as used herein, generally refers to any interaction between a user and a device via a touch screen. A user may enter input by pressing the touchscreen, swiping the touchscreen, drawing shapes on the touch screen, and/or using a tool such as a stylus to interact with the touchscreen. In some embodiments, input may be multitouch (i.e., created by a user pressing two or more points on the screen simultaneously).

Receiving module 106 may receive the input in a variety of contexts. For example, receiving module 106 may be part of an authentication system for the computing device that is expecting authentication input via the touchscreen. In another embodiment, receiving module 106 may be monitoring input to the touchscreen in order to mirror the input before passing the input on to a third-party service that is awaiting authentication information.

In some examples, receiving module 106 may detect that the user has entered a component of the input and provide the user with an acknowledgement that the component of the input has been received by the computing device. For example, if the input includes a password that has multiple letters that a user draws on the touchscreen, receiving module 106 may provide an acknowledgement to the user after every letter. In some examples, each time the user removes their finger and/or stylus from the touchscreen, receiving module 106 may provide an acknowledgement. In some embodiments, receiving module 106 may provide the acknowledgement whether the input is correct or not. In one embodiment, receiving module 106 may provide the user with the acknowledgement by vibrating the computing device. Additionally or alternatively, receiving module 106 may cause the computing device to make a noise, flash a light, and/or provide any other kind of feedback to the user.

At step 308, one or more of the systems described herein may determine that the input from the user may include a mirrored version of the valid authentication input that is flipped along a vertical axis relative to the touchscreen. For example, determination module 108 may, as part of computing device 202 in FIG. 2, determine that input 210 from the user may include a mirrored version of valid authentication input 212 that is flipped along a vertical axis relative to the touchscreen.

The term “mirrored version,” as used herein, generally refers to a version of input that can be represented as a two-dimensional image and that is flipped over one axis. For example, the mirrored version of a touchscreen press in the upper-left corner of the screen is a touchscreen press in the upper-right corner of the screen. In another example the letter “d” is a mirrored version of the letter “b” that is flipped along the vertical axis while the letter “M” is a mirrored version of the letter “W” that is flipped along the horizontal axis. By contrast, the number “6” can be described as a version of the number “9” that is rotated, rather than mirrored, because the change occurs along two axes.

In another example, as illustrated in FIG. 4, a user may use touchscreen 402 to input a shape composed of four lines. If the shape illustrated in the normal version of touchscreen 402 is a user's passcode for a mobile phone, then after flipping the mobile phone over the user may instinctively draw the shape starting from the top left, making a right angle and drawing a line downward, drawing another line to the right, and adding a tail going up and to the right, as they would if the phone were oriented normally. In this example, the resulting shape is the shape in the mirrored version of touchscreen 402, which, relative to the user (who is facing the back of the phone), is the same shape as the normal version, but, relative to the touchscreen that is receiving the input, is a horizontally mirrored version of the valid shape.

Determination module 108 may determine that the input is a mirrored version of the valid authentication input in a variety of ways. For example, determination module 108 may mirror the input and then compare the mirrored input to the valid authentication input. In some embodiments, determination module 108 may mirror several components of the input and then concatenate those components before comparing the concatenation to the valid authentication input. For example, determination module 108 may receive mirrored versions of the characters “p,” “@,” “s,” “s,” and “1,” mirror the received versions to arrive at the actual characters, concatenate the characters to arrive at the password “p@ss1,” and the compare a hash of the word “pass” to the stored hash of the user's password.

Additionally or alternatively, determination module 108 may determine that the input is a mirrored version of the valid authentication input by determining that the valid authentication input is a set of ordered components and determining, for each ordered component within the set of ordered components, that a currently entered component of the input from the user is a mirrored version of the ordered component that corresponds to the correct position in the set of ordered components. For example, if a user is attempting to input the number “1360” on a numerical keypad laid out the same way as touchscreen numerical keypad 502 illustrated in FIG. 5, the user may instead input the numbers “3,” “1,” “4,” and “0,” in that order. In this example, determination module 108 may determine that “3” is a mirrored version of “1,” “1” is a mirrored version of “3,” “4” is a mirrored version of “6,” and “0” is a mirrored version if itself, and therefore the user's input is a mirrored version of the valid input of “1360.”

In some embodiments, determination module 108 may determine that the input is a version of the valid authentication input that is being entered using a different input method than the valid authentication input. For example, if a user normally inputs a passcode via a keypad, a version of the valid input entered using a different input method may include the user drawing the characters of the passcode (in mirrored and/or normal versions) on the touchscreen with a finger and/or stylus.

Returning to FIG. 3, at step 310, one or more of the systems described herein may authenticate the user to the service in response to determining that the input may include the mirrored version of the valid authentication input. For example, authentication module 110 may, as part of computing device 202 in FIG. 2, authenticate the user to the service in response to determining that input 210 may include the mirrored version of valid authentication input 212.

Authentication module 110 may authenticate the user in a variety of contexts. For example, authentication module 110 may authenticate the user to the service on the computing device by unlocking the computing device. In another example, authentication module 110 may authenticate the user to an application and/or a website. Additionally or alternatively, authentication module 110 may open a password-protected file, change a password-protected setting, and/or authorize a password-protected transaction.

In some embodiments, the systems described herein may track a user's input patterns when attempting to authenticate to a face-down device. Because some users may naturally input mirrored versions of their authentication input while other users may not, the systems described herein may track whether a particular user's input is more likely to be mirrored or not and may improve efficiency by first checking mirrored versions of the user's input if the user is more prone to mirrored input and first checking normal versions of the user's input if the user is not prone to mirrored input.

As described in connection with method 300 above, the systems and methods described herein may enable users to intuitively and securely authenticate to their mobile devices in public places by detecting that the device has been flipped over and interpreting the input as a potentially mirrored version of the correct input. By enabling users to intuitively enter a mirrored version of their passcode on a facedown mobile device, the systems and methods described herein may help improve security for users' devices by preventing bystanders from seeing users' passcodes.

Although not required, in certain embodiments computing system 610 may include both a volatile memory unit (such as, for example, system memory 616) and a non-volatile storage device (such as, for example, primary storage device 632, as described in detail below). In one example, one or more of modules 102 from FIG. 1 may be loaded into system memory 616.

In certain embodiments, example computing system 610 may also include one or more components or elements in addition to processor 614 and system memory 616.

Display device 624 generally represents any type or form of device capable of visually displaying information forwarded by display adapter 626. Similarly, display adapter 626 generally represents any type or form of device configured to forward graphics, text, and other data from communication infrastructure 612 (or from a frame buffer, as known in the art) for display on display device 624.

As illustrated in FIG. 6, example computing system 610 may also include at least one input device 628 coupled to communication infrastructure 612 via an input interface 630. Input device 628 generally represents any type or form of input device capable of providing input, either computer or human generated, to example computing system 610.

As illustrated in FIG. 6, example computing system 610 may also include a primary storage device 632 and a backup storage device 633 coupled to communication infrastructure 612 via a storage interface 634. Storage devices 632 and 633 generally represent any type or form of storage device or medium capable of storing data and/or other computer-readable instructions. For example, storage devices 632 and 633 may be a magnetic disk drive (e.g., a so-called hard drive), a solid state drive, a floppy disk drive, a magnetic tape drive, an optical disk drive, a flash drive, or the like. Storage interface 634 generally represents any type or form of interface or device for transferring data between storage devices 632 and 633 and other components of computing system 610.
